Abstract

The problem of increasing yellow coloration of PbWO₄ crystal grown from the melt has been analyzed using a micro-pulling down technique. The ratio of free surface area to melt volume in μ-PD growth is noticeably higher in comparison with CZ method. The incongruent vaporization of PWO melt generates changes in stoichiometry and subsequently causes difficulties for crystal growth from tungsten-excess melt.
